Regarding ODBC entries

Hi All,
I am Repackaging "Brio Intelligence 6.6", But i am not able to get the ODBC Entries in the ODBC Tables of the ISM, But there are entries in registry, i dont want these entries to be in Registry but instead should be in ODBC Tables, Also when i install the MSI, M not able to get the ODBC Entries i.e.. they are not getting installed when i check in the System DSN, but in the Normal vendor setup we can see the entries in System DSN.
Can anyone please tell me how to make changes in ISM or IRP to make the ODBC Entries come in ODBC tables.
